APPARATUS FOR COATING CIGARETTE-PAPER WITH LEAF METAL.

SPECIFICATION forming part of Letters Patent No. 750,255, dated January26, 1904. A li ti fil November 21,1901. Serial No. 83,137. No model.)

To all whom it many 0011420101 lie it known that l. (inouo .\loarrz(Lu.- m-zam. a citizen of the kingdom of Saxony. residing at Dresden. inthe kingdom of Saxony. (ierman Empire. have invented certain new anduseful Improvements in Apparatus for eating Cigarette-Paper with Leaf.\letal: and I do declare the followingto he a full. clear. and exactdescription of the invention. such as will enahle others skilled in theart to which it appertains to make and use the same. t'el'el'etiee heiaghad to the aetaanpaiwing drawings. and to the letters and ligures ofreferenee marked thereon. which form a part of this specification.

Up to the. present time gilded mouthpieees of cigarettes were when nothandwork nnule with the aid of devices in which the leaf metal comingfrom n hohhin wasat regular intervals clamped hy a hlnnt-edged tool(-IIOIHUUHLV called cutter to a tahle or heard helow and then severed ortorn asunder hy the pull exercised on it by the gunnnedcigarette-lullrer. 'lhis tearing asunder prtslnees a very irregular lineof se mration and gives rise to much waste hoth of metal and cigarettes.in order to do away with thesedrawhaeks. the iresent invention separatesthe device for ehee (ing or clamping the leaf metal when it is to hesevered from the device which carries out this severing. attrihut ingthose operations to separate members. Furthermore. the device forsevering is in this invention not merely a hlunt tool clamping the leafmetal to he theren mn torn. hat a memher making a drawing out. and mayconsist in either a straight or circular knife. a saw. a thin wirethread. or the like.

Figure l is a front elevationof the machine with the hlock which carriesthe clampingplates shown in vertical section. Figs. 2 and :t are detailviews. partly in elevation and partly in section. showing two differentpositions of the hlock. Fig. 4 is a side elevation of the hloek andentmr-head with the cutter lowered.

Ahove the tahle 1!. over which the protecting-strip b together with theleaf metal Figs. 2. 3. mere. two clamping-plates 1/ c are movahle upanddown. When the feed of the metal strip is to he arrested. these comedownI on the latter and clamp it to the tahleu. l ig.

2. 1n the meanwhile a knife f between the clamping-plates descends andcuts oil a piece of the leaf metal I! with a drawing cut. the knifeheing adjusted to exactly descend exactly so far as to cut the metalonly, and not the paper I; as well. The leaf metal heing held lirmlyagainst the tahle on both sides of the knife. cannot more under it. andthe result is a elean cut in just the proper place. When the cut iscompleted mul the severed piece of leaf metal is to he pasted on thegununed portion of the eigarettemper passing over the revolving rolleru. the elamping-plates 1/ w are raised as well as the lt'nil'ef to allowthe leaf metal to pass on.

To prevent the metal strip from possihly sticking to the. rear elamp Iwhen the latter rises and disturhing the good operation of the. apmratus. a scraper/1 may he provided. holding down the metal when theelatnps rise.

As the scraper/l and the lt'nit'ej' may receive their motions in anysuitahle manner from other moving parts of the eigarette-maehine. it isnot deemed necessary to give a detailed description thereof. the motionof the knife being only indicated.

The luiifej'consists of a thin steel hlade mounted in a slide 1'. whichmay he moved to aml l'ro hy a red A on the hloek carrying theclamping-plates (I 1.. Inside the slide two side plates m are adjustahlyattached by screws u to the sides of the ltnit'e-hlude r'and may heaccurately adjusted in relation to the block I. the tahle n. and thepaper strip l; with the aid of wedges p and screws I.

The up-and-down motion of the clampingplates is derived from cams I] hymeans of vertically-guided rods 1'. fastened to the hlock in this hloektheelamping-plates are given a certain amount of vertical play aml areactuated upon by springs I. sunk intothe lll()('.l\' land pressingonpins rot the clamping-plates (I I. Thus the latter in coming down on themetal stripesereise an elastic pressureon the same. hut neverthelesselamp it down stillieiently lirmly on the tahle 1/. When the hlock. withits slide 1'. descends. the plates 4/ 1- first clam )the leaf metal. amlthen the knife. moving t own with the hloelt'. comes down on the leafmetal and savers it in eonstamenee of its lateral motion relatively tothe hloelt' Simultanoously with tho tlownwartl motion of thoclamping-plates: the roller .r,wh1ch has to pross tho sovorotl piooeot'loaf motal to tho ,cigarotto-papor strip. is movotl out of contact withtho rollor in ortlor to intorrupt tho food of tho papor strip/1 antl thomotal stripw whilo tho lattor is boing lltlt by the platos 1/ 1' and outby tho hnit'cf'. This motion of tho rollor .r. acting also asguitlo-rollor for tho papor strip l is tlorivotl from a cam rovolvingabout tho contor 1/. ttlltl tho projecting portions of which prossagainst an arm .2 of an oscillating lovor carrying tho rollor .r. andthoroby tomporarily "cmoving tho lattor from tho papor 11-.
